Memorable moment

John was a Jamaican employee at a coffee shop in London in 1963. After ordering a cup of tea, the Doctor asked him where the shop's owner Harry was, then pointed out his wife was about to give birth to twins.

John chatted with the Seventh Doctor about adding sugar to tea, leading the Doctor to muse about the larger ripple effects that occur through time even from small decisions. John's father had worked in the sugar fields in Jamaica. (TV: Remembrance of the Daleks)
